In case of a power failure
The user data settings and registered data for one-touch speed dialing and coded speed dialing
are saved during a power failure using a built-in battery*. However, documents stored in the fax
memory will be deleted and redial data in the extension phone memory may be lost. If a power
failure occurs or the power is turned off, the fax will automatically print a memory clear report
as soon as the power is turned on or the power is restored. This report includes a list of the
documents that were stored in the memory at the time of power failure.
During a power failure _________________________
The following restrictions apply to the function of the fax during a power failure or while the
power is turned off:
• You cannot use the fax to make telephone calls. Also if your fax is connected to a telephone,
you may not be able to make telephone calls.
• You cannot send, receive, or copy documents.
• You can receive voice calls only if a telephone, or an extension phone is connected to your fax.
Memory clear report ___________________________
If you experience a power failure, the documents in the fax memory will be lost.
As soon as power is restored to the fax, it will automatically print out a list of documents that
were stored in the memory at the time of the power failure.
* TAM messages are also saved if the power fails.
If the cartridge is empty or there is no paper in the multi-purpose tray when power is restored, the
memory clear report will not be printed even after the cartridge is replaced or paper is loaded.
